Has anyone else with an S4 B6 have this 'feature'? Get in turn the key, all the lights come on...... and then nothing. For anything up to 10-15 seconds. Then after this delay it fires up no problem as you would expect, not struggling to crank over or taking ages to start.... I have changed the battery with no change. It only seems to do it if its been sitting for a few hours. Any ideas??
